CHAPTER V THE LATER HISTORY OF THE BALLADS BY comparing the different versions of the ballads, the history of many of them can be traced over a number of years. Some have undergone considerable transformations in the three or four centuries during which they have been known. The same kinds of changes seem to take place in all ballads alike, no matter how different their origins may have been. There are three main causes of change: communal recreation, the printing of versions as broadsides, and re-shaping by skilled poets. First, communal recreation. It can be seen in its purest form in the history of ballad music, since the tunes of the ballads were rarely printed before the nineteenth century. I have quoted Sharp's description of the mechanism by which the community exerts its taste by varying and selecting tunes. His description applies to some extent to ballads texts as well. Communal recreation is the means by which a ballad, however learned its origin, loses the signs of individual authorship and takes on impersonality and the other ballad characteristics. It may work for bad or for good. Degeneration often occurs when a ballad gets into oral tradition: not all singers have good memories, references to extinct beliefs may become unintelligible and then corrupt (as in "the cocks are crowing a merry midlarf" for "on merry middle-earth'J), and the poetic sensibility of a community may decline. There is a good deal of rubbish and nonsense in Child's collection, and even more in the modern American collections. On the other hand, communal recreation may sometimes produce a large number of variations in a ballad, each with its own merit; and in these cases it would be impossible to say that any particular variation is the best because it is nearest to a hypothetical archetype. For example, Gerould quotes eight sets of the opening 06
